Int 10 Fn EF - Video - MSherc.com - Get Video Adapter Type And Mode [V]
AH = EFh
Return: DL = video adapter type
00h original Hercules
01h Hercules Plus
02h Hercules InColor???
DH = memory mode byte

Program: MSHERC.COM is a support program for the Microsoft Quick languages which
makes their graphics libraries compatible with a Hercules card by
adding video modes 08h and 88h, and supporting text in the new
graphics modes.
Notes: while in mode 08h or 88h, INT 10 supports the Hercules card much like
a CGA.
MSHERC performs an installation check by setting DL=FFh and testing
whether it has been changed on return
